Résumé Cet article présente le processus de traduction en français du Charcot-Marie-Tooth Disease Pediatric Scale (CMTPedS), le seul outil de mesure validé évaluant la sévérité de la maladie chez les enfants atteints de CMT. Le processus de traduction utilisé s'inspire des lignes directrices de la Food and Drug Administration (FDA). La version préliminaire francophone du CMTPedS a été testée auprès de 14 enfants atteints. Les résultats de l'application démontrent que la passation a été bien tolérée par les enfants et s'est avérée conviviale pour les cliniciens. La disponibilité de cet outil en français semble prometteuse pour le suivi des enfants atteints et la réalisation d'essais clinique.

The French version of the MDHI is an optimal translation of the original instrument that is acceptable to native patients and ready for clinical trial use. Muscle Nerve 57: 686-689, 2018.

Background The childhood phenotype of myotonic dystrophy type 1 (DM1) involves impaired cognitive functioning starting in infancy, which may compromise later on their ability to carry out instrumental activities of daily living (IADLs) necessary for living independently. The current study aims to document the ability to perform IADLs among adults with the childhood phenotype of DM1 and to explore its links to cognitive functioning. Methods This cross-sectional exploratory study was conducted among 11 individuals living with DM1. IADLs related to money management, home management & transportation and health & safety activities were assessed by the Independent Living Scale (ILS). Neuropsychological tests assessed participants’ intellectual abilities and executive functioning. Associations were investigated using Spearman’s rho correlation. Results Important difficulties were found in all three categories of IADLs, mostly in money management in which only 2/11 participants were scored as independent. 8/11 participants showed low to very low intellectual functioning and limit to impaired executive functioning. Apathy was also a common feature as 5/11 participants showed clinical level of apathy. A lower IQ was associated with greater difficulty in the home management & transportation subtest of the ILS. Conclusions Adults with the childhood phenotype of DM1 demonstrate relative dependence in regard to the following IADLs: money management and home management & transportation. Level of dependence is, at least partially, associated with cognitive impairments. The work relates to results from an exploratory study; thus, studies must be pursued to describe in more details difficulties experienced by this population.

Background Autosomal recessive cerebellar ataxias (ARCA) are a group of rare inherited disorders characterized by degeneration or abnormal development of the cerebellum. Autosomal recessive spastic ataxia of Charlevoix–Saguenay (ARSACS) is one of the most prevalent in Europe. Objectives The aim of this study is to provide a better understanding of the manifestations and impacts of ARSACS. Methods A systematic review of the literature was conducted, followed by a qualitative study using semistructured interviews and discussion groups to obtain the experience of people affected. Results According to the PROMIS framework, the results show manifestations and impacts in three components of health: physical, mental, and social. Fatigue and struggles with balance and dexterity are the physical manifestations of the disease most often cited by participants. Negative affects such as frustration and depression are among the mental health impacts with some loss in cognitive abilities. Social health is the least documented component; nonetheless, people with the disease report significant impacts in terms of social relationships, activities and work. Conclusions These findings shed new light on the experience of people with recessive ataxia and identify key aspects to assess to improve their overall health.
